Malcolm Brenner, 63, had a year-long affair with Dolly when he lived at a former theme park in Sarasota, Florida.
He has spoken about his ‘relationship’ and given a graphic account of their sex life as part of a 15-minute short documentary called Dolphin Love.
He said: ‘I started rubbing her along her back, working my way to her flukes – her tail.
‘And as I was rubbing her and moving my hand towards her tail, Dolly was slowly rolling around her long axis.’
He then goes on to talk about icky stuff like genital slits and things start getting somewhat 18-rated with an animation to help assist viewers.Brenner was a photographer at the time in 1971 (a time when such acts weren't illegal) and so had access to the dolphin pool after hours.He said that she ‘announced her intentions to me by positioning herself so I was rubbing against her.’
